For Crohn's Disease, Maintenance I've been on this medicine for 2 months. I feel, most days like I've been in a car accident. The pain is very difficult to handle. I ache like I have the flu. Thinking about not taking good it and take my chances. What could be worse?

For Crohn's Disease, Maintenance This medicine will make you feel like you been hit by a car everyday, exhausted, plus your liver and pancreas take a massive hit. I had constant pain and all my crohns complaints returned, I was fine on prednisone and entocort but my doctor wanted to make it even better.. please pay EXTREME CAUTION using this medicine before ending up in the hospital. I'm not saying this medicine is bad but for one person it seems extremely well or extremely bad, in my case the worst time I ever been through. Pay attention!

For Bacterial Vaginitis Hi ladies! So I had BV and went to doctors to get prescription. The doctor prescribed ONE dose of 2000MG ( 4 pills of 500MG) and take it all at once!!! After day two my symptoms are GONE!!! Maybe the doctor should prescribe one dosage for BV as it's very effective!!!!!!!! Consider it

For Bacterial Vaginitis I had to take 2 g the 1st day and 2 g the second day. Just took the second dose of pills and I feel funny. My head is feeling weird and I feel sleepy. Had dark urine and a bad taste in my mouth - my tongue looks unhealthy too. But damn my vagina is feeling the bomb again. Smell went away right away. Btw I get BV when I am together with a person I don't wanna be with. Just a hint to some baby girls out there. Do you really like him? Cause sometimes the body answers the question for you. Deep. I know.
